Yes death. Yes all who sin must die. Yes, all who die will also be judged. Yes, their flesh will be destroyed by flames and worm will eat their bones, for eternity. This will happen to all whose names were not written in The Lamb's Book of Life. Ignoring that after death comes judgment and eternal conscious torment is not being faithful to The Holy Scriptures. Those whose names are recorded in The Lamb's Book of Life will receive eternal life. Eternal suffering is the only fate found in Scriptures for those who chose death over life.
